I watched the Mario Bros movie as an adult a few years back and really enjoyed it. It was a fun take on the lore!
The only thing I felt was weak was Dennis Hopper. His performance had strong "I'm too good for this" vibes. Based on the other things I know him from, that's wildly untrue - it should have been a great fit for him. Chew the scenery and be an arsehole - basically be the Deacon from Waterworld, or the villain from Speed!
